摘要:
基于安塞县12 a的统计资料，定量评价了安塞县1999—2010年的退耕林生态系统服务价值，并对其外部性价值进行了权重分析和计算，结果表明：安塞县退耕还林已基本达到改善生态环境的首要目的，为区域生态经济发展提供了巨大的生态系统服务价值，总价值为1 027 352万元，其中外部性价值为540 550万元，占总价值的52.62%；各项功能的价值量排序为：固碳释氧 > 涵养水源 > 保育土壤 > 保护生物多样性 > 净化环境 > 森林防护。其中最为重要的固碳释氧主要作用于全国范围内，且总的外部性价值超过了总价值的一半，这表明黄土丘陵沟壑区为黄河中下游地区的生态修复和水土保持贡献了巨大的力量。通过本文的外部性价值计算，估算出安塞县的退耕还林补偿上限应为12 325.5元/（hm2·a）。
Abstract:
Based on statistical data, the value of the Converting Farmland into Forest and Grassland Project of Ansai County in 12 years was quantitatively calculated, also its externalities weight analysis was calculated. The results showed that the Converting Farmland into Forest and Grassland Project of Ansai County has achieved the primary target of improving the ecological environment. This project has provided tremendous value for the local area’s ecological and economic development. Total value was 1.037×1010 Yuan. The externality value was 5.41×109 Yuan, accounting for 52.62% of the total value. The service value of the functions of forests was in the order of: carbon fixation and oxygen release > water conservation > soil conservation > species conservation > environmental purification > action of forest against natural calamities. The most important role was carbon fixation and oxygen release, it played the main role in the nationwide, the external value was more than half of the total value, indicating that loess hilly region contributed to the tremendous power of ecological restoration and soil conservation in the middle and lower reaches of the Yellow River region. Calculated by the the external value, the estimated returning farmland compensation ceiling of Ansai County was 12 325.5 Yuan per hectare.
